Hypothesis
Is the higher mortality rate in Scotland compared to England explained by problem drug use?
Conclusion
Problem drug use significantly contributes to excess mortality in Scotland, accounting for about a third of the difference compared to England.
Supporting Evidence
- 38 deaths occurred in the cohort, with a standardised mortality ratio of 1244.
- 32.0% of the excess mortality in Scotland is due to drug use.
- Only 22 of the 38 deaths were classified as drug related.
Takeaway
In Scotland, many people who use drugs die, and this is a big reason why more people die there compared to England.
Methodology
Secondary analysis of the DORIS cohort study involving drug users in Scotland.
Potential Biases
Potential numerator-denominator bias due to differences in definitions of drug users.
Limitations
The study relies on mortality data that may not fully capture all drug-related deaths due to varying definitions.
Participant Demographics
Mean age of participants was 28, with 69% being male.
